Application filed December 21, 1920.

T0 all fio/20m, t may concern f y Be :it known that l, Darin Gouin-MUM. a citiz u of the United `tit-etes. and a resident of Syracuse, in the county of Onondaga and State of New Yorlr, have invented a certain new and useful Automatic lvlixing and Froportioning Device or Valve, of which the following is a specicat-ion.

This invention has for its object a proportioning and mixing device particularly applicable for p roportioning and combining elements or streams to bemixed in deli nite ratios, and of the type set forth in n y pending application, Sr. No. eil-12,736, filed Sept. 25, i920, which device is particularly adapted for use in larger pipe lines or installations than that shown my pending application, and whicli: is particularly siniple and efiicient in construction and highly efficient and durable in use. It consists. in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing` this invention, reference is had to the accompanying drawings in which like characters designate corresjvmnding parts in all the views.

pumps, or streams of other substances comg bined for any purpose in just the required ratio, in the form. of two concentric conical sheet streams of any desired thickness impinging upon and intermingling` with each other in one stream so as to produce the highest efficiency under all working conditions at full or fractional capacity.

The device consists generally of four concentric cylinders the inner and outer cylinders being stationary and secured together in fixed relation and the other two inner cylinders being for adj ustingthe thicknesses of the streams being mixed. These inner cylinders are preferably adjustable and slide axially but in some instances may be stationary. They may also be separated for variable service when the ratio between the combined streams is to be varied, or they may be cast together in one piece for permanent service.

Each of the two inner regulating or adjusting' sleeves or cylinders has a cone end surface opposed to a cone surface of the outer or the inner cylinder, that is, one of these regulating cylinders has a cone surface opposed to a contracting cone surface of the outer member and the other regulating cylinders has a cone surface opposed to a cone surface on the innermost stationary cylinder. rlhe smaller streams to be combined enters the inner stationary cylinder and it passes between two of such conical surfaces while the larger stream enters the outer stationary cylinder and passes between the other two of such conical surfaces. Thus, the thicknesses of these two streams can be regulated where required by sliding' the two inner regulating cylinders and hence varying the quantities of, and the ratio between the volumes of the combined streams.

By means of the proportioning valve with the two inner regulating cylinders cast in one, that ratio between the passage. areas for the two streams that would produce the highest e'i'l'iciency can be automatically maintained under all working conditions whether the passages are fully open or partly closed. The proportioning valve here shown is especially adapted to flanged pipe connections as for furnace firing and large manufacturing` processes.

This proportioning and mixing device or valve for combining' streams of materials one of the two' CII ifi-ie or fluids to be mixed in fixed ratios comprises generally, inner and outer hollow stationary members or cylinders arranged concentric with each other and formed with passages for the materials or strean'rs to bc inter-mingled within the outer member, the inner member being arranged with its passage substantially coaxially with the pasage of the outer member and havin openings into the passage of the outer "somber, said members having flanges for connection to like flanges of pipes on a pipe line or to the flanges of adjacent devices, means as inner cylinders or sleeves adjustable lengthwise of the inner and outer members to open and close the passage of the outer member more or less and proportionately close the outlet passage of the inner member, and means for effecting the adjusting` movement of the sleeve.

1 and 2 are respectively, the outer and inner members or cylinders, the outer member 1 beingv formed with a contracting or conical. portion 8 confining;- a contracting; passage, the member 1 being also formed with inlets l in the larger cylimler portion thereof above the conical portion 8.

Also, if desired, suitable ribs or flanges G may be located between the inlets -1 of the outer member 1, Figs. 1 and 2 for reinforcement. rllhe outer member 1 is open at its upper or rear end, with respect to the direction of the flow of the materials to be mixed, and is formed with annular flanges 7 and 8 on cach end thereof for connection respectively to the inner member as will be hereinafter de scribed and to a pipe line or to the inner member of another mixing?,` device when the devices are arranged in series as shown in Fig. 8.

The inner member or cylinder 2 is in the form of a tube closed at its inner end and lmving` a series of lengthwise opening slots 10 near its inner end, rl.`he inner member or cylinder 2 has a head 11 between its ends formed with an annular flange 12 opposed to the flanc-e 7 for securement thereto in anj suitable manner by bolts or cap screws. The inner member or cylinder 2 is also formed at its outer end with flange 13 for connection to a similar fiance on the outer member of an adjacent n device when the devices are arranged in series as shown in Fig. 8 or to a pipe line. The inner member is closed at its inner end by a suitable means 141 here shown as of two conical shaped parts, one, 15 being fixed in the slotted end of the member 2 and preferably cast in one therewith, and the other projecting,` axially into the passage of the outer member 1 and being secured to the member 15 in any suitable manner as by a tie bolt 17 18 is one adj usting sleeve member or cylindrical member which encloses the member 21 and is slidable axially of the members 1, 2. 19 is the other adjusting sleeve or cylindrical member, these members in Fig. 1 being shown as formed integral with each other. The sleeve member or cylinder 18 is shown as having an internal conical bore 18L at its inner end overlyingv the slotted end of the .member 2 and the member 19 as having' a conical surface 20 opposed to the conical wall of the contracting portion j rll.`he conical bore 18L is arranged in parallelism to a conical surface 21 on the rear side of the member 1&1- of the inner stationary cylinder 2, this surface being arranged beyond the ends of the slots 10. During movement of the sleeve members 18, 19 inwardly, the surface 18L moves toward the conical wall 21 of the inner stationary cylinder 2, and the conical wall 2O moves in parallelism toward the conical surface of the contracting; portion 8 of the outer cylinder 1 and proportionately closes or opens the outlet passage 22 formed between the surfaces 18a and 21 and leading from the slots 1() of the member 2 and the pas-\ sages 2Oa between the conical face 20, of the sleeve 19 and the wall 3 of the outer cylinder 1. rlhis adjusting member 18 slides on the periphery of collars 28 cast in the member 2, with a packing between.

The means for adjusting' the sleeves or cylinders 18, 19 axially comprises one or more screws 24 having their shanks supported in the head 11 of the inner member 2 and held from endwise movement relatively thereto, the screws threading,` in passages in the member 18. .Thus, during turning of the heads 25 of the screws the sleeve members 18 and 19 will be moved inwardly or outwardly, as the case may be.

ln order to accurately and finely adjust the members 18` 19 a suitable lgraduated gage plate 26, Fig. 2l is provided on theI head l1 around each adjusting screw and also one or more graduated rods 2T project from lugs 28 on the rear end of the members 18, 19 through the head 11 of the inner member. @ne complete turn of the screw 25 moves the adjusting sleeves 18, 19 and the rods 21 axially an amount equal to one graduation of the rods.

ris seen in Fig. 9, a sinele adjusting means may be provided common to all of the screws, this means here shown as consisting` of an annular gear 29 meshing with a pinion 30 mounted on the shank of each screw 24. The internal annular gear 29 is suitably mounted and supported on the head 11. Thus, during turning` of any one screw or of the annular gear 29, the motion thereof will be transmitted to the other screws. The gear 29 is preferably formed with handles as 81.

ln Fig. 4l, a construction is shown in which the two adjusting sleeve members or cylinders 32 and 33 are provided independent of each other, one within the other, the sleeve member` 32 having` a conical surface 34; opposed to the wall' of the contracting portieri 35 of the outer member o6, the outer sleeve sliding on the periphery of a collar 37 provided on the inner sleeve 33 which has aV conical surface 38 opposed to the conical surface 39 on a closure 40 for the inner member. Both sleeves 32,` 33 are operated 4by screws 42, 43 respectively similar to the screws 24A shown in Fig. l. These screws 42, 43 may be provided with suitable gages or micrometers 44 as seen in Fig. 5. By means of the constructions of sleeve members or cylinders shownk in Fig.y 4, the effective areas of the passages of the outer and inner members can be independently adjusted, and the ratio betweenv the two streams varied as' desired.v

In Fig. 7' is shown a construction Ain which the sleeve 45 is fixed and held by suitable screws or bolts 46- to the head 4T of the inner member 48.

In Fig. 8 is shown a series or battery of my mixing` devices connected by flanged pipe connections in one ot which the sleeve member may be fixed' as shownl in Fi '7, and in the other of which the sleeve has adjusting` movement as shown in Fig. l. In the arrangement showny in Fig. 8, the first of the devices in the series, or the device nearest to the fuel tank is provided withan inner adjustable member as in Fig. l, and the other is preferably of the form shown in Fig. 7.

Owing to the concentric arrangement and to the anged ends of the inner' and outer members the device can be readily connected in large pipe lines and the position of thc sleeve member readily adjustable to suit the conditions.

To aid in determining the proper adjustment of the sleeve member or members, an outlet 49 is provided for the mixing chamber 50 of the outer member through which outlet the mixture can be taken and subjected to tests. In the case the mixture is fuel, it can be lighted at the outlet to determine whether it burns properly for heating or lighting purposes or subjected to temperature efliciency tests. rI`his outlet is here shown as formed in the flange 8 and is normally closed by a cap 5l.
